OBJECTIVETo study the effect of catalpol and puerarin freeze-dried powder for injection (CPFPI), a new compound traditional Chinese medicine (TCM) preparation, on coagulability, hemorheology and NO in rats with qi-deficiency and blood-stasis syndrome.

METHODThe model of rats with qi-deficiency and blood-stasis syndrome was established by hunger, fatigue, cold-dampness, panic and high fat diet. Coagulation time (CT) was observed by the glass method, and bleeding time (BT) was measured by tail-cutting method. The effects of CPFPI were also evaluated with prothrombin time (PT), activated partial thromboplastin time (APTT) and thrombin time (TT). HCT was measured by the electric tesistance method, hemorheology indicators were observed by auto-hemorheological instrument. The level of NO in blood serum was measured by NO assay kit.

RESULTCPFPI 65.40 mg x kg(-1) significantly prolonged CT, BT, PT, APTT and TT in rats. The viscosity of whole blood and plasma, hematocrit, erythrocyte aggregation and rigidity index, and reduced viscosity of whole blood in 65.40 mg x kg(-1) groups were lower than model group. CPFPI 65.40 mg x kg(-1) can raise the level of NO in blood serum. 32.70 mg x kg(-1) markedly prolonged CT, PT and APTT and decreased whole blood viscosity, erythrocyte aggregation index and whole blood reduction viscosity.

CONCLUSIONCPFPI has a significant effect in improving coagulability and hemorheology index and enhancing NO content in blood serum.

Hyperlipidemia plays a vital role in cardiovascular disease, and threatens our lives. The aim of this paper is to study the effects of Shuanghua granules on blood lipid in normal mice and different hyperlipidemia models. Acute and endogenous hyperlipidemia was induced in mice with yolk and Triton WR-1339 respectively. The model of hyperlipidemia in rats was set up by feeding high cholesterol diet. Then preventive effects of Shuanghua granules was observed compared with lovastatin and Zhibituo. We found that Shuanghua granules 5.6, 11.3, 22.5 g x kg (-1) could significantly reduce the serum TG level in normal mice (P < 0.01, P < 0.05). No significant difference was found in liver index, serum TG and HDL-C levels. When the mice were treated with either yolk or Triton WR-1339 in the presence of Shuanghua granules, the plasma lipoprotein levels (TC and LDL-C) were significantly reduced (P < 0.01, P < 0.05). Shuanghua granules could reduce the serum TC, TG, LDL-C, MDA, NEFA and liver TC, TG, LDL-C levels, simultaneously raise serum and liver HDL-C, serum SOD, LPL, HL, LA levels of hyperlipidemia rats (P < 0.01, P < 0.05). Shuanghua granules also significantly reduced whole blood viscosity, RV, etaP, IER and IEA (P < 0.01, P < 0.05), and lowered fatty degeneration of liver tissue. Compared with hyperlipidemia model, there was no significant increase in faeces lipoids concentrations. The results confirmed the mechanism of blood lipid regulating effects of Shuanghua granules is probably related with its antioxidation, regulating hemorheology and improving LPA, HL, LA enzymatic activity.

Objective:To analyze the related factors of neurotoxicity induced by oxaliplatin chemotherapy in patients with colorectal cancer and its prevention and treatment strategies.Methods:A total of 300 patients with colorectal cancer treated with oxaliplatin in Zhejiang Cancer Hospital from January 2018 to December 2020 were randomly selected for baseline collection using the convenience sampling method. The occurrence of oxaliplatin-induced peripheral neurotoxicity (OIPN) was statistically analyzed. The factors that affect the occurrence of OIPN were analyzed using univariate analysis.Results:There was a significant difference in OIPN score between patients of different genders, between patients who had different education levels, between patients who had different occupations, and between patients who lived in different long-term residence places ( t = 7.29, 3.39, 2.53, 18.11, all P < 0.05). There was no significant difference in OIPN score between patients adhering to different religion's beliefs, between patients married and not, between patients who lived with and without members, between patients who paid medical costs and not, and between patients who had a previous history of smoking and not ( t = 3.25, 0.37, 0.69, 2.39, 0.15, all P > 0.05). There was a significant difference in OIPN score between patients with different tumor-node-metastasis stages, between patients who received medication via different administration routes, and between patients who received different times of oxaliplatin administration ( t = 8.40, 3.34, 3.49, all P < 0.05). Conclusion:Medical staff should pay attention to the occurrence of OIPN in patients with colorectal cancer treated with oxaliplatin, focus on the patient's factors related to the disease, and take correct and effective coping strategies promptly to reduce the adverse reactions, improve the quality of life, and ensure the therapeutic effect.

Objective To investigate the correlation between claudin-5 level and the risk of hemor-rhagic transformation(HT)in elderly stroke patients after thrombolysis.Methods A total of 192 elderly stroke patients hospitalized in our department from February 2021 to October 2022 were recruited,and divided into HT group(32 cases,including 14 of parenchymal hematoma type and 18 of hemorrhagic cerebral infarction type)and non-HT group(160 cases)according to the results of head CT or MRI 48 h after thrombolysis.The clinical data and serum claudin-5 level were com-pared between the two groups.Multivariate logistic regression analysis was used to identify the in-fluencing factors of HT risk after thrombolysis in elderly stroke patients.Restricted cubic splines were drawn to analyze the correlation between claudin-5 level and HT risk after thrombolysis.Re-sults The HT group had higher proportion of atrial fibrillation,longer onset to thrombolysis time,higher baseline NIHSS score,and fasting blood glucose and claudin-5 levels than the non-HT group(P＜0.05,P＜0.01).Multivariate logistic regression analysis showed that time from onset to thrombolysis(OR=2.589,95％CI:1.202-5.573,P=0.015),baseline NIHSS score(OR=1.415,95％CI:1.213-1.651,P=0.000),and fasting blood glucose(OR=1.552,95％CI:1.014-2.375,P=0.043)and claudin-5 levels(OR=1.174,95％CI:1.076-1.281,P=0.000)were risk factors for HT after thrombolysis in elderly stroke patients.Restricted cubic spline anal-ysis demonstrated that claudin-5 level had a nonlinear relationship with the risk of HT in the pa-tients after thrombolysis(x2=12.380,P=0.006).Conclusion Serum claudin-5 level is associated with HT after thrombolysis in elderly stroke patients,and shows a dose-response relationship with HT.

Closed-loop hospital management can effectivly cope with the COVID-19 pandemic. In order to ensure the continuity of treatments for hemodialysis patients under closed-loop management and minimize possible medical and infection risks, Huashan Hospital affiliated to Fudan University and 9 hospitals in Shanghai established a hemodialysis alliance in January 2021.The alliance optimized hemodialysis resources within the region through overall planning by preparing sites, materials and personnel shifts in advance, and establishing management systems and work processes to ensure that patients could be quickly and orderly diverted to other blood dialysis centers for uninterrupted high-quality hemodialysis services, in case that some hemodialysis centers in the alliance under closed-loop management.From November 2021 to April 2022, 317 of 1 459 hemodialysis patients in the alliance were diverted to other centers for treatment, accumulating 1 215 times/cases of treatments without obvious adverse reactions. The practice could provide a reference for medical institutions to quickly establish mutual support mode under major public health events.
